Abstract (en)
[origin: US4360635A] Transparent thermoplastic moulding compositions having improved mechanical properties consist of graft copolymers or mixtures thereof with a cellulose ester of aliphatic C1-C5 carboxylic acids, wherein the graft copolymers consist of an ethylene vinyl ester copolymer and a cellulose ester of aliphatic C1-C5-carboxylic acids as the graft substrate, at least part of which being bridged with polymerized grafted units of vinyl esters and/or alkyl esters of acrylic and/or methacrylic acid, and, optionally, C2-C4-olefins.
